    Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5,

def task2(rows, cols):
    """
    Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array.
    The element value in the i-th row and j-th column of the array should be i*j.
    Note: i=0,1.., X-1; j=0,1,¡­Y-1.

    Example:
    Suppose the following inputs are given to the program: 3, 5.
    Then, the output of the program should be:
    >>> task2(3, 5)
    [[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]]

def task3(password):
    """
    A website requires the users to input username and password to register.
    Write a program to check the validity of password input by users.

    Following are the criteria for checking the password:
    1. At least 1 letter between [a-z]
    2. At least 1 number between [0-9]
    3. At least 1 letter between [A-Z]
    4. At least 1 character from [$#@]
    5. Minimum length of transaction password: 6
    6. Maximum length of transaction password: 12

    Your program should accept a password and will check them according to the above criteria.

    Example:
    If the following passwords are given as input to the program: ABd1234@1,a F1#,2w3E*,2We3345
    Then, the output of the program should be:

    >>> task3('ABd1234@1')
    True
    >>> task3('a F1#')
    False
    >>> task3('2w3E*')
    False
    >>> task3('2We3345')
    False
